摘  要:目的:建立高效液相色谱法测定大鼠组织样品中花椒麻素含量的方法。方法:采用Intersil ODS-sPC18(250mm×4.6mm,5μm)为分析柱,流动相甲醇-水(70:30,V/V),流速0.5mL/min,检测波长254nm。结果:心、肝、脾、肺、肾脏、脑、胃、小肠、脂肪、肌肉、皮肤、睾丸及前列腺的线性范围分别为0.1~10pg/mL(r=0.9986)、0.1~50pg/mL(r=0.9999)、0.1~10μg/mL(r=0.9997)、0.1~10μg/mL(r=0.9989)、0.1~20μg/mL(r=0.9993)、0.1~10μg/mL(r=0.9995)、0.1~100μg/mL(r=0.9999)、0.1~50μg/mL(r=0.9982)、0.1~20μg/mL(r=0.9956)、0.1~10μg/mL(r=0.9988)、0.1~10μg/mL(r=0.9997)、0.1~10μg/mL(r=0.9998)及0.1~10μg/mL(r=0.9998)。方法平均回收率大于82%,日内日间变异均小于11%,稳定性良好。结论:本方法准确、快速、重复性好,适用于大鼠组织样品中花椒麻素含量的测定。Objective: To develop a sensitive and selective high performance liquid chromatography (HPLC) method for identification and quantification of alkylamide from Sichuan pepper (Zanthoxylum bungeanum) in various tissues of rats administered with it. Methods: Chromatographic separation was performed on an intersil ODS-SP C18 column (250 mm × 4.6 mm, 5 μm) using a mobile phase composed of a mixture of methanol and water with a ratio of 70:30 (V/V) at a flow rate of 0.5 mL/min. The detection wavelength was 254 nm. Results: Good linearity was obtained for alkylamide in heart, liver, spleen, lung, kidney, brain, stomach, small intestine, fat, muscle, skin, testicular and prostate over the ranges of 0.1-10 (r = 0.998 6), 0.1-50 (r = 0.999 9), 0.1-10 (r = 0.999 7), 0.1-10 (r = 0.998 9), 0.1-20 (r = 0.999 3), 0.1-10 (r = 0.999 5), 0.1-100 (r = 0.999 9), 0.1-50 (r = 0.998 2), 0.1-20 (r = 0.995 6), 0.1-10 (r = 0.998 8), 0.1-10 (r = 0.999 7), 0.1-10 (r = 0.999 8) and 0.1-10 μg/mL (r = 0.9998), respectively. The average recovery rate of the method was over 82%, the intra- and inter-day precisions (RSD) were both smaller than 11%. Alkylamide from Sichuan pepper was proved to be stable during sample storage, preparation and analysis periods. Conclusion: This method is accurate, rapid and reproducible, and can be applied to determine the content of alkylamide from Sichuan pepper in tissues rats administered with it.
